What should be paid attention to during the operation of high-speed die-cutting machine?

High-speed die-cutting machine is the key equipment for efficient processing of materials (such as paper, film, adhesive, etc.) in packaging, printing and other industries. It has high running speed and high precision requirements, and its operation and maintenance should strictly follow the specifications to ensure production safety, product quality and equipment life. The following are the core issues that need to be paid attention to during operation:

First, the preparation work before starting.

equipment inspection

Check whether all mechanical parts (such as die, pressing roller and feeding mechanism) are firmly installed, and there is no looseness, deformation or wear. In particular, the cutting edge of the die should be sharp and without gaps to avoid burrs or material sticking during die cutting.

Make sure that the lubricating system (such as guide rail and gear) has sufficient oil, and fill the corresponding type of lubricating oil according to the requirements of the manual to prevent the parts from being damaged due to dry friction.

Check that the electrical system (such as power supply, sensor and control system) is connected normally, and the emergency stop button and safety protection device (such as protective cover and infrared sensor) are in good condition to ensure that the machine can be stopped immediately in case of emergency.

Material and parameter confirmation

Check whether the specifications (thickness, size, material) of the materials to be processed match with the cutter die, so as to avoid the damage of the cutter die or the overload of the equipment caused by the excessively thick/hard materials.

Parameters such as die-cutting pressure, speed and feeding accuracy are preset according to material characteristics. Before the first operation, trial cutting can be carried out to observe the quality of incision and feeding stability, and gradually adjust to the best state.

Second, the operation specification in operation

Safety protection

It is forbidden to put hands and tools into dangerous parts such as feeding area and die cutting area when the equipment is running. If it is necessary to clean up waste or adjust, you must first press the emergency stop button and cut off the power supply.

Operators should wear necessary protective articles (such as gloves and goggles), and their long hair should be tied up to avoid being involved in transmission parts.

real-time monitoring

Closely observe whether the material conveying is smooth, whether there is deviation, wrinkle, jamming and other phenomena, and stop the machine immediately once it is found, so as to prevent the equipment from being overloaded or the tool die from being damaged due to material accumulation.

Check the product quality after die cutting, if there are any problems such as missing cutting, irregular trimming, too deep/too shallow indentation, etc., adjust the pressure and speed in time or replace the die.

Pay attention to whether the running sound of the equipment is normal. If there is abnormal sound (such as metal rubbing sound and impact sound), abnormal vibration or peculiar smell, it is necessary to stop the machine immediately for investigation to avoid the expansion of the fault.

waste treatment

Clean up the waste produced by die cutting in time to prevent it from accumulating on the feeding channel or die cutting table, which will affect the material conveying accuracy or cause equipment blockage.

Third, the maintenance after downtime

Equipment cleaning

Clean up the dust, paper scraps and oil stains on the surface and inside of the equipment after shutdown, especially clean up the residual waste on the die cutter and press roller to prevent corrosion or affect the next use.

Wipe and lubricate sliding parts such as feed roller and guide rail to ensure smooth operation next time.

Parameter reset and recording

Before turning off the power supply of the equipment, reset the operation parameters to the initial state to avoid the failure caused by parameter errors when starting the equipment next time.

Record the product model, parameter setting, problems and treatment methods of this operation, so as to facilitate follow-up traceability and optimization.

Periodic inspection

According to the requirements of the equipment manual, regularly check the wear and tear of key components (such as cutter dies, bearings, transmission belts and sensors), and replace the aged or damaged parts in time to ensure the long-term stable operation of the equipment.

summary

The safe operation and efficient production of high-speed die-cutting machine depend on strict inspection before starting, standardized operation in operation and timely maintenance after stopping. Operators should be familiar with the characteristics of the equipment, keep a high degree of vigilance, and handle problems in time when they find them, which can not only ensure personal safety, but also prolong the service life of the equipment and improve the product quality.
